Tomorrow I'll be on ice machine cleaning duty. I've read a lot on here about how dirty they can be and how a lot of refrig. mechanics won't get ice in their drinks, etc. unless it's from a unit they service. I want to do it up right.
What I usually do is (and this is generic, we have 3 different machines): Empty the bin and drain it. Then, follow manufacturer's directions for cleaning with nickel safe ice machine cleaner. This usually entails turning the unit off, adding the ice machine cleaner, then switching the unit to "clean" and allow the cleaner to circulate for 15-20 minutes. Then, I purge the system of the chemical and flush with water for 4 or 5 minutes. If I still see any hard water residue, I repeat the same process. After that's finished, wipe out the bin with a bleach/water solution.
Is there anything else I could/should do?
